We had difficulty with this type of indication for 2 years. After
having the experts check it out, we finally reread the manual.
There are many wires in the control box inside the locker on the
starboard side-under the catch all shelf. One was actually totally
loose. Resecuring this solved the problem. Of course we did check
all the other connections as well. But we did not realize that
there are around 12 wires inside the box. Lots of margin for error,
corrosion, and dislocation. Noelia-
